CDR KombuchaLab the easy-to-use analysis system to optimise your kombucha production process by obtaining results in real time.

Determination of Fermentable Sugars in Kombucha

Kombucha is a fermented beverage obtained from tea and added sugars (mainly sucrose). It is advisable to check the evolution of the fermentation process, promoted by the symbiosis of bacteria and yeasts used to produce it, in order to be able to stop it once the optimal sugar level has been reached which allows the desired taste and organoleptic characteristics to be obtained. Furthermore, the analysis of sugars allows the prompt recognition of a possible fermentation arrest.


Test Principle

Fermentable sugars (glucose, fructose and sucrose) in the presence of NAD+ react with glucose oxidase, developing NADH. The concentration expressed in g/L is determined through the stoichiometric ratio 1:1 with the total quantity of sample sugars.

Calibration Curve

The calibration curve of the CDR KombuchaLab  instrument, obtained by comparing the CDR method with the enzymatic method for the determination of glucose, fructose and sucrose, confirmed an excellent linearity of the system over the entire measurement range.
